Cl has an atomic number of 17 and an atomic mass of 35. How many
lubasha [3.4K]

Answer:

7 Electrons

Explanation:

Assuming that final energy level is that same as valence shell, we first need to find how many of the electrics will be used to fill the ones before it.

Electron shell capacities are as follows :

First shell/Ebergy level: 2 electrons

Seconds shell/energy level : 8 electrons

Third shell /energy level :8 electrons

The first two shells total to 10, and the first three shells total to 18. Since chlorine (17) fills more than 2 shells but less that 3, the third one is its final energy level. We find the number in the final energy level by subtracting the 10 in the full first two. 2+8=10

17-10=7

Chlorine has 7 electrons on its final energy level.

Hope this helped!

lateral inversion

<u>Explanation</u>

The image formed by a plane mirror is formed at equal distance from the mirror as the object is.

The size of the image is the same as the size of the object.

The image is laterally inverted. This means that, when  a person lifts his right hand, his or her image will raise it's left hand.

solmaris [256]

Answer:

Toasting in a toaster is usually considered  by (infra red) radiation. But the hot coils touch the toast so an element of heating by conduction occurs as well.
